Description

Technical Field

[0001] This utility model relates to the field of overload protectors that can be remotely controlled to reset after power failure, and specifically to an overload protector that can be remotely controlled to reset after power failure. Background Technology

[0002] To protect electrical appliances from overheating damage caused by changes in home or ambient temperature, overload protectors are often installed in these appliances. With the widespread use of electrical appliances, overload protectors are now commonly used in motors, transformers, rechargeable batteries, and other household appliances. Currently, overload protectors are available in both automatic and manual reset versions. Automatic reset overload protectors, under overload conditions, frequently disconnect and reset, easily causing overheating and aging, reducing the appliance's lifespan. Manual reset overload protectors require opening the appliance casing and manually pressing a reset button. This is generally inconvenient for non-professionals and requires professional repair, making it difficult to use. Furthermore, general overload protectors have poor sensitivity to low overload conditions. Utility Model Content

The live wire interface is located on the right side of the housing, and the neutral wire interface is located on the left side of the housing. The live wire interface and the neutral wire interface are symmetrically distributed on the upper and lower sides of the housing.

[0007] The short-circuit protection device includes a first conductor and an electromagnetic coil. The electromagnetic coil is located at the bottom of the first conductor and is electrically connected to the electromagnetic coil. An L-shaped plate is provided at the bottom of the electromagnetic coil. A central lever is provided at the bottom of the L-shaped plate. A C-shaped rod is provided at the top of the central lever. The top and bottom ends of the C-shaped rod are fixedly connected to the central lever and the bimetallic strip, respectively.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the top and bottom of the inner side of the housing are provided with wiring grooves, the wiring grooves are fixedly connected to the housing, and the first guide plate is located at the bottom of the wiring groove and is electrically connected to the wiring groove.

[0010] The further beneficial effect of adopting the above method is that, by electrically connecting the first conductive piece to the wiring slot, current can flow into the first conductive piece through the wiring slot.

[0011] Furthermore, a screw is provided on the side of the wiring slot near the live wire interface and the neutral wire interface, and the screw is threadedly connected to the wiring slot.

[0012] The further beneficial effect of this approach is that by connecting the screw to the wiring slot via a threaded connection, tightening the screw can secure the wire connected to the wiring slot.

[0013] Furthermore, the L-shaped plate is electrically connected to the electromagnetic coil.

[0014] Furthermore, an iron core column is provided inside the internal hole of the electromagnetic coil, and the iron core column is in clearance fit with the electromagnetic coil.

[0015] The further beneficial effect of adopting the above method is that, through the gap fit between the iron core and the electromagnetic coil, the iron core can slide within the electromagnetic coil.

[0016] Furthermore, a push rod is provided at the bottom of the iron core column, and the push rod is fixedly connected to the iron core column.

[0017] Furthermore, a second spring is provided between the bottom of the iron core column and the L-shaped plate, the push rod is located inside the second spring, and the push rod passes through the L-shaped plate and is in clearance fit with the L-shaped plate.

[0018] The further beneficial effect of adopting the above method is that the second spring between the bottom of the iron core column and the L-shaped plate can support the iron core column and limit its movement, preventing the iron core column from sliding down. When the electrical appliance is short-circuited, the electromagnetic coil will generate a strong magnetic field that will pull the iron core column down, causing it to overcome the elastic force of the second spring and fall down.

[0019] Furthermore, a voltage sensor and a temperature sensor are provided on the right side of the electromagnetic coil. The voltage sensor is electrically connected to the electromagnetic coil, and the temperature sensor is fixedly connected to the outer casing.

[0023] Furthermore, an arc-extinguishing grid is provided on the top of the second guide plate, and the arc-extinguishing grid is electrically connected to the second guide plate.

[0024] The further beneficial effect of adopting the above method is that, by electrically connecting the arc-extinguishing grid with the second conductive plate, current can flow from the second conductive plate into the arc-extinguishing grid. At the same time, the arc-extinguishing grid can eliminate the residual arc after the circuit is cut off, thus effectively protecting the equipment.

[0025] Furthermore, a fifth guide plate is provided on the far left of the arc-extinguishing grid, the fifth guide plate being electrically connected to the arc-extinguishing grid, and a third guide plate is provided at the bottom of the fifth guide plate, the third guide plate being electrically connected to the fifth guide plate.

[0027] Furthermore, a wire is provided at the bottom of the third guide piece, and the wire is electrically connected to the third guide piece.

[0028] The further beneficial effect of adopting the above method is that the wire is electrically connected to the third conductor, allowing current to flow into the wire through the third conductor.

Furthermore, by setting the bimetallic strip, the heat generated by the wire after overload will cause the bimetallic strip to bend downwards, and drive the C-shaped rod to rotate the central lever counterclockwise, thereby disconnecting the second and third conductors and ultimately breaking the circuit.

[0031] Furthermore, the fourth guide plate has a fixing rod at the end away from the wiring groove, and a fixing seat at the bottom of the fixing rod. The upper and lower ends of the fixing rod are fixedly connected to the fixing seat and the fourth guide plate, respectively.

[0033] The further beneficial effect of adopting the above method is that the central lever is rotatably connected to the outer casing via the second pivot, allowing the central lever to rotate around the second pivot.

[0034] Furthermore, a C-shaped push block is provided on the side of the central lever away from the L-shaped plate, and the C-shaped push block is rotatably connected via a first rotating shaft.

[0039] The further beneficial effect of adopting the above approach is that the PLC control chip enables the equipment to control its internal devices in real time, thereby increasing the controllability of the equipment.

[0040] Furthermore, a first spring is provided at the bottom of the central lever, and the two ends of the first spring are respectively rotatably connected to the third guide plate and the central lever.

[0041] The further beneficial effect of adopting the above method is that, by setting the first spring, the end of the third guide plate away from the fifth guide plate is lifted upward, so that it is in close contact with the second guide plate.

[0042] The further beneficial effect of adopting the above method is that, by setting up the C-shaped rod, the rotation of the central lever can affect the bimetallic strip.

[0043] Furthermore, a voltage sensor is provided at the bottom of the housing, and the voltage sensor is fixedly connected to the housing.

[0044] The further beneficial effect of adopting the above is that the voltage sensor enables the device to detect the internal voltage in real time.

[0045] Furthermore, the back of the outer casing is provided with a slot, which is trapezoidal and extends through the outer casing.

[0046] The further beneficial effect of adopting the above is that the design of the card slot facilitates the fixing and disassembly of the device.

[0047] The beneficial effect of this utility model is that, through the above design, it provides an overload protector with remote control for power failure and reset. Firstly, by default, the electric push rod is in a retracted state. The lower end of the C-shaped leg block, hinged to the hinge seat, abuts against the central lever, pressing the central lever downwards. This causes the third guide plate to rise under the action of the first spring and contact the second guide plate, allowing current to flow normally. When a short circuit occurs, the electric coil generates a strong magnetic field that pulls the iron core column downwards. The iron core column then descends against the spring force of the second spring, causing the push rod below the iron core column to push the central lever counterclockwise, driving the third guide plate downwards. This moves the third guide plate away from the second guide plate, ultimately breaking the circuit. When an overload occurs, the heat generated by the wires causes the bimetallic strip to bend downwards and, through the C-shaped rod, drive the central lever counterclockwise, causing the third guide plate to descend and disconnect from the second guide plate. The device communicates with a mobile phone via a control panel, and data detected by the internal temperature and voltage sensors are displayed on the phone in real time. If the device experiences an overload, a notification will be sent to the phone as an alarm. Users can manually disconnect the circuit via their phones. When a user activates the circuit disconnect button, the electric push rod pushes the C-shaped push block forward, causing it to rotate counter-clockwise around the first axis. The end of the C-shaped leg closest to the iron core column lowers the iron core column, while the end closest to the central lever rises, causing the iron core column to overcome the second spring and push the central lever to rotate counter-clockwise, ultimately disconnecting the third guide plate from the second guide plate. When the user reconnects the circuit, the electric push rod retracts, causing the C-shaped push block to rotate smoothly. The end of the C-shaped leg closest to the iron core column rises, while the end closest to the central lever falls, thus reconnecting the third guide plate to the second guide plate.

[0082] For details, please refer to the appendix. Figure 1-5As shown, the working principle of this utility model is as follows: This utility model provides an overload protector that can be remotely controlled to reset after power failure through the above design. By default, the electric actuator 20005 is in the retracted state. The lower end of the C-shaped leg block, which is hinged to the hinge seat 20007, abuts against the central lever 20006 and presses the central lever 20006 downward. This causes the third guide plate 30001 to rise under the action of the first spring 20003 and come into contact with the second guide plate 20012, allowing current to flow normally. When a short circuit occurs, the electric coil will generate a strong magnetic field that pulls the iron core column 20010 downward. This causes the iron core column 20010 to descend against the elastic force of the second spring 20014. The actuator 20013 below the iron core column 20010 pushes the central lever 20006 to rotate counterclockwise and causes the third guide plate 30001 to descend, moving the third guide plate 30001 away from the second guide plate 20012, ultimately breaking the circuit. When an equipment overload occurs, the heat generated by the wire 30006 will cause the bimetallic strip 30002 to bend downwards and drive the central lever 20006 to rotate counterclockwise via the C-shaped rod, thereby causing the third guide plate 30001 to descend and disconnect from the second guide plate 20012. The device communicates with a mobile phone via a control panel, and the data detected by the internal temperature sensor 10011 and voltage sensor 10009 are displayed on the mobile phone in real time. Once the device is overloaded, a notification will be sent to the mobile phone to trigger an alarm. Users can actively disconnect the circuit via their mobile phones. When a user activates the circuit disconnect button, the electric push rod 20005 will push the C-shaped push block forward, causing the C-shaped push block to rotate counterclockwise around the first rotating shaft 20008. The end of the C-shaped leg that is close to the iron core column 20010 will cause the iron core column 20010 to descend, while the end that is close to the central lever 20006 will rise, causing the iron core column 20010 to overcome the second spring 20014 and descend, pushing the central lever to rotate counterclockwise. Finally, the third guide plate 30001 will disconnect from the second guide plate 20012. When the user reconnects the circuit, the electric push rod 20005 will retract, causing the C-shaped push block to rotate. The end of the C-shaped push block near the iron core column 20010 will rise, while the end near the central lever 20006 will fall, thereby reconnecting the third guide plate 30001 with the second guide plate 20012.
